Question
Write the definition of wave front.
✓

Answer

"In any medium in which a wave is propagating, if we draw a surface on which all the particles located are in the same phase of vibration, then such surface is called 'wave front'." The wave front of a wave in a homogeneous medium is always perpendicular to the direction of wave propagation.
